How to improve the work efficiency of the bending machine

    How to improve the efficiency of the hydraulic sheet metal bending machine in the bending process? Before using the hydraulic sheet metal bending machine to bend the material, various data needs to be adjusted, including the bending force, the distance of the back gauge, and the slider The adjustment of the upper limit, the speed of the slider and the gap between the upper and lower molds, etc., make it meet the actual operation requirements. How to calculate the bending force of the bending machine among these parameters?

    The calculated pressure of the hydraulic sheet metal bending machine is calculated based on the tensile strength of the sheet. If your board performance is different, although the calculation is the same, the actual force required by the bending machine is naturally different. If the external factors are the same, it is only a problem with the bending machine, which can be adjusted in two places. One is to adjust the tensile strength of the panel in the system, and the other is to adjust the DA value in the system settings.

When the hydraulic sheet metal bending machine descends rapidly, on the one hand, the oil pump supplies oil to the cylinder through the synchronization valve, and on the other hand, the top oil tank 1 feeds oil to the cylinder through the one-way valve 2 through the natural height difference. Jointly supply oil to the upper cavity of the oil cylinder to achieve the purpose of rapid descent of the oil cylinder. Because the flow in the valve circuit after passing through the synchronization valve is approximately equal, only the flow from the oil tank to the oil cylinder 3 through the one-way valve 2 is considered. For the inlet pressure of the two one-way valves, P1 can be atmospheric pressure, so it is equal.

　 How to use hydraulic sheet metal bending machine:

　　Common hydraulic bending machine processing Q235 sheet to make a brief introduction:

　　 1. First, turn on the power, turn on the key switch on the control panel, and then press the oil pump to start, so you can hear the sound of the oil pump rotating. (The machine does not operate at this time)

　　2. Stroke adjustment, you must pay attention to adjusting the stroke when using the bending machine, and you must test run before bending. When the upper die of the bending machine descends to the bottom, there must be a gap of plate thickness. Otherwise it will cause damage to the mold and the machine. The stroke adjustment also has electric quick adjustment and manual fine adjustment.

　　3. For the selection of bending notches, a notch with a width of 8 times the thickness of the plate is generally selected. If you bend a 4mm sheet, you need to choose a slot of about 32.

　　 4. Back gauge adjustment generally has electric quick adjustment and manual fine adjustment, the method is the same as the shearing machine.

　　5. Step on the foot switch to start bending. The bending machine is different from the shearing machine. You can release it at any time. When you release your foot, the bending machine will stop and continue to go down when you step on it.

　Debugging and operation of hydraulic sheet metal bending machine:

1. After the hydraulic bending machine is installed and leveled, first wipe off the anti-rust oil on the sliding and processing surfaces of the hydraulic bending machine, and carefully clean it. According to the equipment lubrication diagram, refill the sliding parts as required Suitable lubricating oil.

　　2. Check the firm bolts at each joint to prevent the loosening caused by transportation and hoisting from affecting the use and safety of the hydraulic bending machine.

　　3. Clean the oil tank, check the filter screen, and fill in sufficient hydraulic oil as required. According to the instructions, add hydraulic oil to the oil return point of the oil pump.

　　4. Check the electrical components, connect to the power supply after confirming that there are no safety hazards, start the motor, and after confirming that the oil pump rotates correctly, perform dry operation for three minutes.

　　5. Select the electrical button to the inching position and step on the foot switch to allow the hydraulic bending machine to go up and down several working strokes under no load to check whether the electrical appliances and hydraulic components are working properly.

　　6. Trial folding: According to the thickness and length of the plate, choose a reasonable lower die V-groove and hydraulic press brake pressure. The trial folding plate should be thin first and then thick, and the pressure should be small first and then large, in order to check the execution of commands by various components.
